The most romantic gesture in the universe
Flowers die in a week. Jewelry sits in a box. A restaurant reservation is forgotten by Tuesday. But a love letter traveling through deep space at the speed of light? That's forever. Literally.
Your words are encoded as a radio signal and transmitted at 1420 MHz toward the star of your choice. The signal moves at 299,792 km/s — racing outward from Earth, passing the Moon in 1.3 seconds, the Sun in 8 minutes, and Mars within the hour. By tomorrow, your love letter will be further from Earth than any human has ever traveled.
In a thousand years, when everything else is dust, your love letter will still be traveling through the galaxy. That's not poetry. That's physics. And it starts at $19.

Perfect for Valentine's Day, anniversaries, and proposals
Valentine's Day — The ultimate Valentine's gift. "I sent our love letter to Alpha Centauri." It will arrive in 4.37 years. Check the tracker together every February 14th and see how far your love has traveled.
Wedding anniversary — Especially meaningful for milestone anniversaries. A 10th anniversary love letter to Vega. A 25th to Polaris. A 50th to the center of the galaxy. The tracker becomes an annual ritual — watching your shared message travel further every year.
Proposal — Propose with a framed Transmission Certificate that says "Will you marry me?" aimed at a star. The Signal Tracker becomes a countdown to the wedding — "Our proposal is now 47 million km from Earth."
Wedding gift — Give a newlywed couple a love letter to the stars on their behalf. Their love, traveling through the universe together. The framed certificate ($99) makes a stunning display piece for their new home.
New relationship — It works just as well for early romance. "I know this is new, but I wanted to do something that would last." Bold move. Big payoff.

Write whatever you feel
Up to 500 characters — enough for a meaningful love letter, not so much that you overthink it. Some of the most beautiful messages we've seen are just a few words:
"I love you more than the distance between here and Alpha Centauri."
"You are my North Star."
"42 years together. Still my favorite human."
"I knew the moment I saw you."
Others write longer messages — a paragraph expressing everything they feel. Inside jokes that only two people understand. A memory from their first date. The thing they love most about their partner.
The message can be public (shown on the Signal Explorer) or completely private — your choice. Most love letters are kept private, but some couples love the idea of their words being publicly visible in the cosmic record.

The framed certificate — the ultimate romantic keepsake
For the ultimate romantic gesture, choose the Framed tier ($99). Your Transmission Certificate arrives museum-quality, professionally framed, ready to hang. It documents a real physical event:
• Your love letter (exactly as transmitted)
• Both your names
• The destination star and its distance in light-years
• The transmission date
• Station coordinates
• Signal frequency (1420 MHz)
• A unique SHA-256 cryptographic verification hash
Hang it above the bed, in the living room, in a hallway, wherever your love story lives. It's the kind of artifact that becomes a family heirloom — something your grandchildren will see and ask about. "Grandpa sent grandma a love letter to the stars. It's still traveling."

A shared tracking page
Both of you get access to the Signal Tracker — a live page showing exactly how far your love letter has traveled from Earth. Updated every second.
Check it on your anniversary each year. Watch it pass the Moon, then Mars, then Jupiter, then leave the solar system entirely. Each anniversary, the number is bigger. The message is further. The love is literally traveling further every moment.
It becomes a ritual — the most unique anniversary tradition in the world. "Where's our love letter now?" Pull up the tracker and see: 2.3 billion km. Next year: 11.8 billion km. The year after that: past Neptune. It never gets old, because the numbers never stop growing.
This is what makes a love letter to the stars different from every other romantic gift. It's alive. It changes. It grows. It's a living connection to your message, updating in real-time, forever.

Which star for a love letter?
Each destination carries different romantic symbolism:
Alpha Centauri — The nearest star. "Even at the speed of light, nothing can separate us." Arrival: 4.37 years. Close enough to feel intimate.
Vega — One of the brightest stars in the sky. In Chinese mythology, Vega represents Zhīnǚ (the Weaver Girl), separated from her lover across the Milky Way. A star with romance woven into its mythology for thousands of years.
Polaris — The North Star. "You are my Polaris." A guiding light through everything. 433 years travel time — the love letter arrives in the year ~2459.
Deep Space — No destination. Just love, released into the universe, traveling forever. The most poetic option for couples who don't need a target — just the act of sending.
Sagittarius A* — The supermassive black hole at the center of our galaxy. For love with gravitational force. "My love for you is 4 million solar masses." Big energy. Literally.

Why it resonates so deeply
We've given a lot of thought to why love letters to the stars create such a strong emotional response. Here's what we think it is:
Scale. The contrast between the intimacy of a personal love note and the incomprehensible vastness of deep space creates a kind of emotional vertigo. Your most personal words, traveling through the largest thing that exists. The private made cosmic. The small made infinite.
Permanence. Every love story fears the same thing: ending. A love letter in space doesn't end. It doesn't fade. It doesn't get lost or thrown away or forgotten in a drawer. It travels at the speed of light, further every second, for millions of years. It's the closest thing to eternal that physics allows.
And there's something about the act of sending — not receiving. You write the words, you choose the star, you release the message. It's an intentional act of love aimed at the cosmos. That intention, that deliberateness, is what makes it feel so meaningful.

Couples who send together
Some couples send two messages — one from each person — aimed at the same star. Two love letters, traveling in parallel through space at the speed of light, in the same direction, forever. Together.
Each gets their own Signal Tracker, their own certificate, their own message. But the signals travel side by side. It's a beautiful metaphor for partnership: two individual voices, same direction, same speed, same journey.
Some couples also create matching framed certificates and display them together. Others send a joint message and frame it as a shared artifact. Both approaches work beautifully.
Whether it's a time capsule of your relationship at this exact moment, or a message meant to travel forever, the shared experience of choosing words for the stars is uniquely bonding.
